PVC-U and PVC-M pressure pipes are suitable for use at service temperatures up to 50Â°C. For PVC-O pipes, the maximum continuous operating temperature should be limited to 45Â°C.
Friction loss (psi/100 ft) and velocity for water flow in plastic PVC pipe schedule 40. The diagram below indicates friction loss for water flow through plastic schedule 40 PVC pipe. The calculation is based on the Hazen-Williams Equation with a Hazen-Williams coefficient c = 140.Velocities between 7 to 10 feet per second are common.riction loss (psi/100 ft) and velocity for water flow in plastic PVC pipe schedule 40.
